摘　　要：中色非矿谦比希铜矿东南矿体深部地压活动频繁,并受顶板上方含水层的影响,生产风险较大。针对东南矿体复杂的地质条件,提出了联合传统地压监测手段、微震监测手段综合监测东南矿体深部地压的方案,提高了地压监测预警的准确性和可靠性。研究结果表明:盘区间柱附近的地压活动较强烈,主要是受周围生产扰动影响,但幅度不大;微震监测结果与传统地压监测结果相符,且微震监测能够提前2天左右感知地压活动的情况,具有一定预见性;将传统地压监测与微震监测相结合,能够提高地压监测预警的准确性和可靠性,该综合监测方法一定程度上能够保障矿山的安全生产。The deep ground pressure activity in the southeast ore body of theNFCA Qianbixi Copper Mine is frequent,and affected by the aquifer above the roof,the production risk is greater.In view of the complex geological conditions of the southeast ore body,a scheme was proposed to comprehensively monitor the deep ground pressure of the southeast ore body by combining conventional ground pressure monitoring methods and microseismic monitoring methods,the accuracy and reliability of ground pressure monitoring early warning were improved.The results show that:The ground pressure activity near the interval column is relatively strong,mainly affected by surrounding production disturbances,but the amplitude is not significant;The results of microseismic monitoring are consistent with those of conventional ground pressure monitoring,and microseismic monitoring can perceive ground pressure activity about 2 days in advance,which has a certain degree of foresight;Combining conventional ground pressure monitoring with microseismic monitoring can improve the accuracy and reliability of ground pressure monitoring and early warning,and the comprehensive monitoring method can ensure the safe production of mines to a certain extent.
